Help Identifying I2C Sensor from Propel Star Wars Drone

I have a sensor from a Propel Star Wars drone that I can't identify. The metal part of the sensor is marked with "A6103 040". I have tried various libraries and sensors, including BME280, BMP280, BMP388, BME680, MPU6050, MS5611, HTU21D, LPS22HB, and MS8607, but none have worked. Does anyone have an idea what sensor this could be or has experience with similar sensors used in Propel drones?

The sensor has an I2C address of 0x76 and shows the following register values:

Thank you for any help!

Here are some photos of the sensor and the board:



Looks like a BMP180 pressure sensor. Altimeter?

I agree. The reviews say altitude and speed are limited.

Here is the datasheet for the BMP180. The circuit board looks like the recommended setup with 2 caps.

I have tried multiple libraries and sensors, including BME280, BMP280, BMP388, BME680, MPU6050, MS5611, HTU21D, LPS22HB, and MS8607, but none have worked.

I also tried BMP180 libraries on an Arduino Uno with the unknown sensor. The result was: begin() failed. Check your BMP180 interface and I2C address.

The back of the PCB is labeled: ADF16102C ST-V2 20161010. There are only two capacitors and the sensor itself.

Thank you for any help!

Hey, I discovered that the sensor is an SPL06-001.
I can read some values and altitudes:
20:22:58.391 -> Measured Air Pressure: 979.22 mb
20:22:58.391 -> Local Airport Sea Level Pressure: 1011.30 mb
20:22:58.391 -> altitude: 271.1 m
20:22:58.391 -> altitude: 889.4 ft
